PRINTING PRESS.

Application filed September 8, 1922. Serial lo. 585,868.

To all whom it may concern.'

Be it known that I, Gnonoa SAoUn, a citizen of the United States, and a resident of Oakes (Highland Post-Oiclel), in the county of Ulster and State of ew York, have invented certain new and useful Improvements in or Relatin to Printing Presses, of which 'the followlng is a specifcation.

The invention comprises anew method of and novel apparatus for cleaning all of the inked surfaces of a printing press,Y includin the form-cylinder and ink-distributing ro 1ers, while the same are on the press and driven from the mechanism thereof.

VMany attempts have been made to eiiciently clean composition ink-distributing rollers and the other inked surfaces of a printing press, and these attempts have met with diiliculties, especially when thel efforts have been to clean the ink-distributing rollers while on the press.

One ofthe diiiculties encountered in the vattempt to clean the composition ink-dis,` tributing rollers while on the press arose 'from the fact that the solvent .was dis tributed along the whole length of one or vmore of the rollers and the scraper was ap plied along the whole length of the roller. This method of procedure resulted in the composition rollers becoming so lubricated with the solvent that the gear-driven steel rollersV merely slipped on the composition rollers without drlving the same. One attempt to remedy this difliculty was to change the mechanism of the press so that all of the composition rollers instead of being frietionally driven by the metal rollers, were e uipped with gear wheels so that they. could e gear-driven. y

In accordance with my invention I do not modify the construction or mechanism of the press, but apply a series of spiral Scrapers thereto, there being one scraper the whole length of the composition roller v but apply the same by a step by step pro.-l

cedure, along the length of the roller, in harmony with the gradual application of the spiral scraper blade to the roller along its length, so that the scraper blade acts progressively and along that ortion of the roller which is receivin the so vent, the surface of the roller bot in advance and in rear of the portion thereof receiving the solvent and in en ement with the scraper being left in con 'tion to frictionally coact with the metal roller from which it receives motion.

The mechanical features of my invention may be built into the printing ress or applied to the same as an attac ment after the press has been built.

In thedrawings I illustrate my invention applied to the. press shown as an attachment, the press havin already been constructed and in use, an .my invention havlng been a plied to the press for eiiciently cleaning t e form cylinder and ink-distributing rollers while on and driven by thel press. In `applying my attachment to the press shown 1n the drawings no change :Whatever was made in the press nor in the arrangement of the ink-distributing rollers.

My invention is intended for resses having different systems of ink-distrlbuting rollers from that shown in the drawings, and thereforel I do not limit the invention to the particular press or arrangement of d'istributing rollers shown in the drawings.

The invention will be yfully understood lfrom the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Fig. 1 is alongitudinal vertical section through a printing press equipped withV the inked-surface cleaning-mechanlslil embodying my invention, the press itself being of ordinary type, the section cutting oil' the front side frame of the ress and the form cylinder and rollers being shown in end elevation;

Fig. 2 is a like view taken from the other side of the press, the side frame of the press at that sidevbeing cut ofl' to disclose the features of my invention, and the ends of the rollers and the end of the form cylinder vshown in Fig. 2 being the opposite of the ends thereof shown in F1 1,

Fig. 3 is a detached v1ew of one of the Scrapers;

Fig. 4 is a side elevation, artly broken away and partly in section, o the same, vtogether with adjacent portions of the frames in which the ends of the scrapers are pivot-ally mounted, the section being on the dotted line 4-4 of Fig. 1;

Fig. 5 is a vertical transverse section through the same taken on the dotted line 5-5 of Fig. 4;

Fig. 6 is a corresponding section through the same taken on the dotted line 6-6 of Fig. 4, and

Fig. 7 is a like section through the same taken on the dotted line 7-7 ofa Fig. 4.

In the drawings, 10 designates a portion of the frame of a printing press, 11 the ink fountain, and 12 the form cylinder, while 13, 14, 15, 16, 17 and 18 respectively designate customary metal ink distributing rollers, which are positively gear-driven as usual, by the mechanism of the press, all the features indicated being of well-known character and arrangement.

The composition ink distributing' rollers at the upper side of the press are numbered, respectively, 19, 20, 21, 22, 23, 24 and 25, and the composition ink distributing rollers at the lower side of the press are numbered, respectively, 26, 27, 28, 29, 30 and ,31,fand all these composition ink distributing rollers are of known type and arrangement and in themselves constitute no part of my invention. 'lhe composition ink distributing rollers just referred to are further indicated in Fig. 1 by the presence thereon ofarrows, which also denote the 'direction of rotation of said rollers, and all of these composition rollers are driven by their frictional engagement with the metal ink-distributing rollers, as usual.

My invention has reference to means for cleaning the form cylinder 12 and all of the ink distributing. rollers simultaneously while said cylinder and rollers are being driven by the press.

In carrying out my invention I mount adjacent to the inner faces of the opposite sides of the press two correspondingly shaped plates 32 of the irregular outline, more clearly illustrated in Fig; 2, to receive the rockable Scrapers hereinafter described, althougli I may say that the outlines of these plates are unimportant so long as said plates, at their edges escape the shafts of the ink distributing rollers and permit the proper positioning of the features of my invention. The plates 32 for different presses will necessarily vary in outline because different presses have different numbers of ink distributing rollers and different dispositions thereof. My invention is applicable for' efficiently cleaning the ink vdistributing rollers. and other inked surfaces of the press, regardless of the number of rollers used and regardless of their particular arrangement with relation to one another. The plates 32 therefore shown in the drawings have an outline signed for and applied to a printing press of the construction shown, but these details will necessarily be modified in form and relation to suit other presses to which the invention is equally applicable.

- I mount in bearings pivotally held in the plates or frames 32, a series of transverse Scrapers 35, there being one scraper adjacent to and for each of the composition rollers of the press, and the details of one of these Scrapers being shown in Figs. 3 to 7 inclusive. The Scrapers 35 are rockable so that they may be moved into operative relation to the composition rollers whenever it is desired to clean the same and the form cylinder and thereafter be retired therefrom, and the means for turning said Scrapers into operative position and retiring the same therefrom' consist of a series of cranks or levers connected with said Scrapers at one side of the press and links connecting said levers so that all of the scrapersmay be operated in unison from one source of manually applied power, as, in the present instance, a rod 36 connected to the lever 37 of one-scraper and having a threaded outer end on which is mounted a hand-wheel 38 whose hub is internally threaded and which is confined in a fork 39, whereby on the rotation of said wheel in one direction the rod 36 will be moved inwardly and turn the lever 37 to apply its scraper to the adjacent roller 25 and through the link-and-lever connections shown cause all the other Scrapers to be applied to their respective rollers, and

on the rotation of said wheel in the reverse direction said rod will be drawn outwardly and turn the lever 37 to carry its scraper from the roller 25 and to ellect through the connected series of links and levers, the retirement of all the other Scrapers from their respective rollers. In Figs. 1 and 2 all of the Scrapers 35 are shown as retired from their respective composition rollers or in an initial position ready to be moved into engagement with said rollers.

The Scrapers are all alike in respect to their construction and mode of operation and a description of one of said Scrapers will answer for all of them, and after one of the Scrapers has been described I will point out the lever and; link connections whereby all the scrapers have simultaneous motion imparted to them from a single manually operated element of the mechanism.

Referring to Figs. 3 to 7 inclusive, 40

designates the scraper blade, 41 a backing plate to which the. blade 40 is adjustably. secured and which is U-ed at its lower portion, as at42, to form a trough, and 43 main supporting end frames substantially conformln to and receivin the end portions of t e plate 41, whic is secured to said frames 43 by means of rivets or screws 44. The blade 40 is secured to the plate 41 by means of screws 45which pass through vertically elongated slots 46 in the blade (Fig. 4), wherezby the blade may be adusted vertically to properl set the outer e ge of the same with relation to 4the composition roller it is designed to clean. The blade 40 is slightly longer than the roller it isto clean and is rounded olf at the ends of its operating edge, as, at 47, to avoid injury'to the roller.

The blade 40`has a spiral set, as I represent in Figs. 5, 6 and 7, which show several sections ofthe blade and indicate the relative positions thereof, Fig. 5 illustrating the set of one end of the blade, Fig. 7 that of the other end of the blade and Fig. 6 that of the middle ofthe blade. The spiral formation of the blade 40 is gradual and uniform from one end to the other thereof and is not of great extent, as lmay be seen on reference to Fig. 3 and lalso by a comparison of the end portions of the blade shown in Figs. 5` and7. The spiral formation of the blade 40 constitutes an important feature of my invention.

The end frames 43 are castings and they cradle the end portions of the plate 40 and its trough 42, and said frames 40 are formed at their outer ends with corresponding extensions 4`8'Which haveilattened sides and respectively enter. bearing sleeves 49, 50 rotatably mounted in apertures in the plates 32. vThe bores 51 of the sleeves 49, 50 have flattened sides to snugly receive the sides of the extensions 48 but loosely enough `to permit said extensions to have a transverse sliding moveinent in' said bores, which are elongated beyond the dimensions of said extensions, as shown in Figs. 4 and 5. I preferably line the fiat sides. of the bores 51 with smooth flat face plates 52 against which theL fiat sides of the extensions 48 have sliding engagement. Within the bores 51 I arrange cushioning springs 53 below and preferably partly entering the extensions 48, as shown in Fig. 4, to cushion the engagementof the edge ofy the blade 40 with the roller it is to clean and to render the blade self-adjustable to the roller.'

The sleeves 49, 50 are positioned in thev line 4-4 of Fig. 1, and the position of this scraper with relationto the roller 19 is clearly illustrated in Fig. 1. The sleeve 50 at one end of the said scraper 35 is,I as shown in Fig. 4 as well as in Fig. 1, formed with a crank-arm '56, Whose connection to the source of manually applied power will be presently referred to.

All of the vScrapers 35 are mounted in the plates 32 in the manner illustrated in Fig. 4, and the tubular bearing sleeves 50 for all of the Scrapers have crank-arms formed thereon adapted to receive link connections whereby all of the Scrapers will be given substantially corresponding motion from-the operating rod 36. The rod 26 is pivotally connected with the bell crank lever 37, as shown in Fig. 2, and by starting with the lever 37 one may follow the lever and link connections throughout the system thereof. The bellcrank lever 37 is connected with the scraper 35 for the roller 25, and the arm 57 of said bell-'crank lever 37 is connected by a link 58 with a lever 59 on the bearing of the scraper 35 for the composition roller 31, as shown in Figs. 1 and 2, whereby said scraper for the roller 31 is given simultaneous movement with the scraper 35 for the rollerA 25. The lever 59 is of bell-crank type and the arm 60 thereof is connected by a link 61 with a lever 62 on the tubular bearing of the scraper 35 for the composition roller 30, and said lever 62 is connected by a link 63 with the lever 64 of the scraper 35 for the composition roller 29, and also by a link 65 with the lever 66 of the scraper 35 for the composition roller 27. The lever 64 isof bell crank type, and one arm thereof is connected by a link 67 with the lever 68 of the scraper 35 for the composition roller 28. l.

The ar`m 57 of the initial operating lever 37 is also connected by a link 69 with the lever 70 of the scraper 3 5 for the composition roller 24, and said lever 70 is connected by a link 71 with the bell crank lever 72 of the scraper 35 `for the composition roller 22. One arm of the lever 72 is connected by a link 73 with the lever 74 of the scraper 35 for the composition roller 23.

The lever 59of the scraper for the roller 31 is connected by a link 75 with the bell crank lever 76 of the scraper for the composition roller 21, and one arm of the lever 76 is connected by a link 77 withthe lever 78 of the scraper for the composition. roller 20. The lever 78 is connected by. a link 79 with the lever 56 of the scraper for the composition roller 19, and said lever 78 is also connected by a link 8O withthe lever 81 of the scraper 35 for the compositionk roller 26.

It will thus be seen` that the manually operated rod 36 communicates motion to the bell crank lever 37, and that from this lever, through the series` of links identilied and the levers of the Scrapers, motion ments.

is simultaneously imparted to all of the Scrapers of the series for all of the composition rollers, all of said Scrapers receiv` ing the same movement as the scraper 35 connected With the prime lever 37. The system of links and levers shown in Fig. 2 permits me to rotate or rock all of the Scrapers 35 with relation to their respective composition rollers, all of the Scrapers operating in unison and having like move It is the purpose of my invention that all of the inked surfaces of the press, including the form cylinder and ink distributing rollers, Shall be simultaneously cleaned while on and driven Aby the press, and hence I Vprovide that all of the scrapers 35 shall operate together and from a sin le source of manually applied power. I eem it essential that the Scrapers 35 be manually operated, since the thorough cleaning Yof the press requires only a few minutes and because I deem it better that the operator may obserfe the progress made in the cleaning of the press andapply the Solvent and Scrapers in such manner as to assure t-he rapid and eicient cleaning of all the ink, paper-dust and the-like, from the inked surfaces of the press.

In the operation of cleaning the press I first throw out the impression cylinder from the form cylinder and cut out the mechanism of the ink fountain so that no ink will be fed during the cleaning operation. This leaves the form cylinder and all of the ink-distributing*rollers in their normal position and relation, and during the cleaning process, the mechanism of the press being in motion, the metal ink-distributing rollers will be gear-driven, as usual, and the composition ink-distributing rollers' will be driven by their' frictional engagea"i ment with the met-al ink-distributing rollers.

One operator will, by means of the lhand Wheel 38, rod 36, `and the series of link and lever connections hereinbefore referred to,. rotate or rock the Scrapers 35 in la direction toward their re'spective composition rollers, and another operator will apply insolvent, such as kerosene, or any of the other known solvents, gradually along the surface of one of the composition rollers. It is almost unimportant to which. of the composition rollers the Solvent may be manually applied. The solvent may be applied. for illustration, to the composition roller 22. In carrying out my method the manner of applying the solvent to the roller 22 and the movement of the Scrapers to the rollers are matters of importance. The Scrapers 35 are spiral, in respect to the blades 40 and troughs 42, and the Iscraper blades 40 will at one end reach and lact against the composition rollers in advance of the 4other portions of said blades Y`reaching said rollers, so that there will be a gradual application of the scraper blades along their length to the rollers, this being a feature of importance.

The solvent is applied to the roller 22, or any other roller of the Series, at the end thereof at which the scraper blade 40 first engages the roller, there beinga gradual traveling application of the solvent along the roller 22 in a direction from said end thereof in about the Same proportion as the Scraper hlade40 is rocked toward and engages successive portions of the surface of said roller, the applications of the solvent being on successive Sections of the roller in harmony with the approach of successive sections of the spiral blade 40 to and against the roller. The scraper blade 40 iS rocked toward the roller 22 in timing with the application of the solvent to and along successive portions of the roller, so that when the solvent is being applied to the far end of the roler that portion of the scraper blade 4() which was initially farthest from the roller 22 will engage said roller. Itv will thus be seen that the solvent is not applied along the Whole surface of the roller 22 or other roller at one time and that the scraper blade 40 does not engage the Whole length of the roller at once, but has a gradual movement toward and against the same. The operating rod 36 will be continued on its inward movement until the scraper blades 40 of all of the Scrapers have along their full length moved, with a continuous traveling engagement, against the rollers and have passed beyond their engagement with the rollers, and at this time I reversely repeat the cleaning operation by moving the rod 36 outwardly to reverse the direction of motion of lthe scraper blades against their rollers and apply the solvent as before but commencing at the opposite end ofthe roller 22 from that to which the solvent was applied in the first stage-of the cleaning operation,

and during this reverse motion of the Scrapers the solvent will be gradually ap-v plied along the roller 22 in timing with the engagement with the roller of successive portions of the scraper blades, the out- Ward movement of the rod 36 being continued until the Scrapers have retired from the rollers and are back to their initial position shown in Fig. 1. If for any reason the rollers should not by this timehave been entirely cleaned, the two Stages of the cleaning operation just described may be at once repeated. I have found that in the space of five minutes the press having the rollers Shown in the drawings and equipped with my mechanism, may be etliciently cleaned. The ink on the rollers is softened by the Solvent applied thereto, nd the foreign matter removed by the scrap rs passes into the. troughs 42 which may be Vcleaned but as often as may be necessary. It is of importance that my method of cleaning' the rollers be followed, that is the radual application of thc solvent along the ength of a feed roller, as 22, and the gradual application of the scraper blade to the roller along that portion thereof which is receiving the solvent. The solvent applied to one of the rollers, as 22, is quick y distributed to all of the rollers, as well as to the surface of the form cylinder, and hence solvent applied to any one section of the roller 22 will almost immediately appear on the corresponding section of all of theother rollers and also of the form cylinder.

In accordance with my method of procedure I do not apply the solvent a ong the whole length of the roller, as 22, selected to initially receive the solvent, but, as aforesaid, apply the solvent by degrees and gradually along the length of the roller 22 while causing the corresponding approach of the scraper blade to the roller, with the result that at all times there are abundant surfaces of the rollers lacking the solvent to assure the continued rotation of the composition rollers, by their frictional engagement with the metal rollers. The solvent is along progressive sections of the composition rollers removed by the scrapers, the solvent being applied to the feed roller at successive sections thereof and transferred to the other rollers at like sections thereof from one end to the other of said rollers and then in like manner back tothe first end of the rollers, as often as may be necessary, and the surfaces of the rollers both in advance and in rear of the portions thereof in engagement with the Scrapers being left in condition to frictionally coact with the metal rollers, wheref by the composition rollers yremain in rotation during the cleaning operation.

During the cleaning of the rollers and Vform cylinder the ink and solvent on the form cylinder transfers to the composition rollers 23, 24, 25, 29, 30 andV 31, and the ink on the steel distributing rollers like- Wise transfers to the composition rollers with which they are in frictional engagement, and the solvent and ink on the composition rollers are removed from each roller by the scraper provided therefor. The composition rollers act to draw or feed ofi the solvent and ink from the form cylinder and steel distributing rollers, and hence when the ink and solvent are removed from the composition rollers, the entire inked surfaces of the press become clean. I apply only a small quantity of solvent at a time to the roller 22, or other selected composition roller of the series, since the solvent becomes quickly distributed from the successive sections of the supply or feed roller to corresponding successive sections of all of the other rollers and to the form cylinder of the press.

My invention provides a new method for the cleaning of the inked surfaces of the press and also novel means for carrying the invention into effect, the new method consisting in the application of the solvent to successive sections of a rotating composition roller along the length thereof and the application of successive sections of the scraper blade to the roller at those successive portions thereof receiving the solvent, leaving the other portions of the roller free for frictional engagement with the adjacent roller by which it is driven or rotated.

I do not limit my' invention to all of the special details of form and construction hereinbefore described, since I am aware that the same may be modified Within the s irit of my invention and the scope. of t e appended claims. I desire to receive adequate protection for my invention.
